This second novel in the Foundation series (Prelude to Foundation and Forward the Fondation are actually prequels) is where Asimov begins to play with the idea. The first bit is in the style of the first series of stories, where a problem is met and measured, and the Fouundation comes out on top. But then he begins the tale of the Mule, one personality so powerful that he alone is able to throw the Seldon Plan off track.
And it is then that you learn of the Second Foundation, the other mysterious group that Seldon supposedly founded... and that nobody has heard of since. Because they, too, have a stake in the future of humanity, and nobody knows quite what that is...
